Terminal 1 is the original terminal at Dublin Airport. However, T2 was built on the approach to T1, which means you’ll pass the newer facility on your drive in. That being said, each terminal has its own dedicated approach, so traffic is rarely an issue.
If you are driving in, you’ll find parking facilities for each terminal. The situation is only slightly more complicated if you are flying into Terminal 1 and need to Transfer to Terminal 2 for Aer Lingus or transatlantic flight. If your airline is assisting you with the transfer, this will all happen behind the scenes.
If, on the other hand, you have to collect your bags and exit security first, then you can connect from T1 to T2 via the new covered walkway. After collecting your bags, enter the Arrivals area, turn right and take the escalator up to the Departures area. The walkway is clearly signposted. The terminals are close together, so there is no need for a shuttle bus.
A walkway between Dublin Airport’s Terminals 1 and 2 is available for those who have not yet passed through the security checkpoint. However, those landing at Terminal 1 and departing via connecting flight from Terminal 2 do not need to make use of this exit. In this case, the route that you need to take will be signposted, and the cabin crew from your previous flight will help you make the proper connections.
If you land at Terminal 1 and would like to pay a visit to Terminal 2 before continuing into Dublin city proper, the walkway is ideally located. Once you pass the security checkpoint baggage reclaim area, make a right-hand turn and take the escalator up to the Departures area on the floor above. The entrance to the walkway is across from Check-in area 1.
This is a covered, glassed-in walkway suitable for all weather. There is also an outdoor path connecting the two terminals for those want to get some fresh air. The route is clearly signposted.
If you can’t find the walkway, a customer service representative (CSR) will be nearby to direct you.
